Below are a few snippets from recent posts, in no particular order, that had
me saying to myself "does not anyone remember an interesting alternative I
thought had come up on NANOG a few years ago?" Well maybe it was some other

Just knowing your spacing and were to places perforated tiles is very
helpful in maxmizing air and not shortcycling it..

Calculating heat
Calculating heat load in a datacenter is pretty easy. That's not the hard part.

The simplest equation to use assumes that you know how much power is going into

In modern data Centers drop ceiling is installed. The reason being you

While all the below is true, I would put forward that many of us
networking types, especially those who operate their own datacenters,
generally know how to do an approximation. Afterall, if you don't have
an idea of magnitude, if you haven't done your homework, your
